I'd agree with the removal of size='-1'. That's basically telling the browser that you'd like the font to be one size smaller than what the user prefers.

Most browsers (at least, those that display in a GUI) specifically have an option for defining two default fonts -- that of 'normal' text, and that of 'fixed-width' text (which gets shown for <tt><pre> and the like.)

I'd suggest that anyone who views code in a web browser set their fixed width font to whatever they use in their text editor for coding, or command line terminal, or however else they're used to interacting with code.

I personally prefer ProFont (although, I like the classic, to the updated version. There's also Sheldon (available from the ProFont page), Anonymous, and I'm guessing plenty of other fonts with a similar purpose.
